zend-expressive does not come out of the box with a console for handling cli commands. However it's easy to add this and make full use of the container and its dependencies.

He uses the Symfony console component to handle most of the "heavy lifting" with the command line interaction, pulled in via Composer. He shows the process for getting the component installed and how to create the "bootstrap" file needed to build an instance of the Application class. He follows this with a simple "greeting" command including the configuration to add a few arguments and output the simple "Hello" message. He then creates the functionality to wire it in to the Zend Expressive application and gives an example of it in use.
